A pressure compensator (100) for providing pressure compensation for a chamber (220) of a subsea device (220) is provided. The pressure compensator has an enclosure (30) with at least an outer wall (31). A first compensation chamber (10) is provided inside the enclosure. A flow connection (40) from the first compensation chamber towards the chamber of the subsea device is further provided. As second compensation chamber (20) is provided inside the enclosure. First and second separating walls (11, 21) are arranged inside the enclosure. A first bellows portion (12) of the first separating wall and a second bellows portion (22) of the second separating wall are deformable to provide pressure compensation between the chamber of the subsea device and a second inner volume around which the second separating wall extends. |
